In the past few years, In Vitro Fertilisation (IVF) has gained popularity as a reproductive treatment for couples who are unable to conceive. In India, IVF has emerged as a beacon of hope for many, offering the chance for parenthood when natural conception is not an option. But, what is the success rate of IVF and what determines it? Age is one of the important elements that impacts success and the second is the number of embryos transferred. This article highlights India’s success rate with IVF segregated by age and number of embryos to show what the prospects are and what can be done to increase chances.
Understanding IVF and Its Significance
IVF is defined as a process whereby an egg is fertilized by a sperm outside the body in a laboratory dish. Following fertilization, the embryo is then implanted back into the uterus of the woman with hopes of achieving a successful pregnancy. IVF is frequently used as a last resort, and average success differs greatly with respect to many factors.
Factors That Affect IVF Success Rates
As success with IVF can differ from one provider to the other, there are other factors to also consider. These include the woman’s age, her overall health, embryo count and quality, along with the health of the eggs, whether they are fresh or frozen.
IVF Success Rates in India
A purposive sampling of fertility clinics in India shows that many have embraced technologies used in other parts of the world and are subsequently adopting the best standards of practice. With advancements in technology and a greater understanding of reproductive health, IVF performed and administered in India has vastly improved. It is safe to say that many women and even those with advanced medical complications are able to achieve pregnancy as IVF success rates in India remain consistently high.
IVF Success Rates by Age
In India, all women of advanced reproductive age face two main obstacles when undergoing assisted reproductive techniques like IVF, outdated medical practices and lack of proper treatment protocols along with their own age. IVF outcomes depend aging women’s egg supply which also depreciates with time. Now, looking at the data, this is how the success rates pan out:
Women Under 30: Women aged under 30 tend to have the best chances of succeeding with IVF and therefore the bulk of its success. Their egg quality and quantity is adequate, and success rates are expected to be in the range of 70 and 75 percent.
Women Between 30-35: This age group tends to experience a slight decline in success rates, but they still have a reasonable achievement rate of 65–70%. This is still a good window for undergoing IVF, however, women may start to experience a reduction in egg quality.
Women Between 36-40: For this age group, success rates drop further to about 50-60%. The current stage of life is marked by approximate skeletal maturity, which means quality and quantity of eggs will greatly decline and the odds of a successful pregnancy will be significantly lower.
Women Over 40: The success rates of IVF performed on women aged over 40 is as low as 40-50%. The quality and quantity of the eggs a woman has at this stage is critically reduced, not to mention there is an increased risk of genetic diseases in the embryos.
A woman’s age influences the total and quality of her eggs which subsequently affects the development of an embryo. Generally, younger women are more likely to have higher chances of a successful fertilization due to having more viable eggs.
IVF Success Rates by Embryo Count
Embryo count refers to the number of embryos transferred during an IVF cycle. The general consensus is that transferring several embryos increases the chance of pregnancy, but it is also controversial.
One Embryo: Single embryo transfers, or SET, have become increasingly common due to advancements in embryo selection and genetic screening. The success rates for single embryo transfers are between 35 to 45%, depending on the woman’s age and quality of the embryo.
Two or More Embryos: The chances of achieving pregnancy can also be increased by transferring two or more embryos. SET success rates are approximately 40 to 50%, while the success rate with three embryos can rise to 50-60%. However, multiple embryo transfers do pose an increased risk of multiple births, which can then lead to complications.
Quality trumps quantity, and genetically tested or blastocyst cultured embryos have higher chances of being successful. This makes the clinic’s capacity to successfully culture high-quality selected embryos so vital.
Factors That Affect IVF Success Rates Based on Embryo Count
IVF success is dependent on the quantity and quality of embryos which are constructed. A thorough genomic assessment, like Pre-Implantation Genetic Testing (PGT), has the potential to optimize the selection of embryos intended for transfer. Furthermore, the time of embryo transfer (blastocyst stage or otherwise) significantly influences the chances of successful implantation.
The Impact of Modern Technologies on IVF Success Rates
Success rates have markedly improved now due to the advancements made in PGT, embryo freezing, and global PGT. The postponement of IVF treatments is made possible with the freezing of embryos. Genetic testing permits one to identify ‘normal’ embryos wherein higher rates of successful implantation and lower rates of an impending miscarriage are expected.
Change of Lifestyle to Improve IVF Success Rate:
IVF success rates can be impeded by some lifestyle factors. Following a healthy diet, engaging in physical exercise, and maintaining a calm demeanor can benefit the outcome of the IVF cycle. Moreover, one should steer clear of tobacco smoking, limited alcohol intake, and maintain the recommended body mass index.
Selecting the Best IVF Clinic in India
Getting the best IVF clinic can make a difference in achieving success. In India, the best clinics have a track record of overall high success rates. Especially make sure they have seasoned staff and provide excellent attention to patient service. It is important to understand the success rates of the clinic in relation to your age and health factors.
In Summary
The average success rates of the in India IVF clinics differs with age of the woman, the middle aged women do best. Women IVF patients but younger than 30 usually achieve the treatment success best. The elder patients have the greatest obstacles. Also, success rates depend on the quality and quantity of embryos obtained. Due to agreed and emerging technologies in this field, it is more easier to achieve successful treatment for most women, regardless of age.
